Expected number of exoplanets binned by radial velocity semi-amplitude K_∗ induced on their host star for all rocky exoplanets (R_p ≤ 2 R_Earth) assuming a planet density of ρ_p = 5000 kg m^-3 (blue histogram). The percentage of exoplanets that is detectable with our space-based MIR interferometer at quadrature (in at least one of the three simulated filters) in addition to radial velocity is shown by the green histogram. The red vertical line indicates our baseline radial velocity detection threshold of K_∗ ≥ 10 cm s^-1.
